Pi Sigma Alpha ( or PSA), the National Political Science Honor Society, is the only honor society for college and university students of political and social sciences in the United States. Its purpose is to recognize and promote high academic achievement in the field of political science. It is a member of the Association of College Honor Societies (ACHS) and adheres to all the standards set by ACHS for an upper-division, specialized honor society. Pi Sigma Alpha is not a social fraternity or club. Chapters The first chapter of Pi Sigma Alpha was founded in 1920 at the University of Texas at Austin, and the society has grown over the years to nearly 850 chapters (as of 2020). A local chapter may be established at any college or university granting the baccalaureate or higher degrees, which is accredited by a regional or national accrediting association, and which offers a major sequence of courses in political science through an appropriate administrative department, school, or division of the institution, and which conforms to other requirements established by the Executive Council of the society. Chapters are guided by faculty advisors and by student officers. Membership There are three classes of membership in Pi Sigma Alpha: student, faculty, and honorary. Student membership is open to juniors, seniors and graduate students currently enrolled in institutions where the chapters are located, who meet the following qualifications: For undergraduates, completion of ten semester-credits or fifteen quarter-credits in political science, including at least one upper-division course, with an average grade of B or higher in all political science courses, and an overall GPA placing the student in the top one-third of his or her class. Individual chapters may raise the eligibility threshold; they may not lower it. For graduate students, completion of nine graduate credits in political science with no grade lower than a B in those courses. Faculty in political science departments where chapters are located are automatically eligible for membership in the honor society. Honorary membership is intended for persons of recognized ability and achievement in the field of political science. No more than two such honorary members may be elected by a local chapter in any one year. Election to membership may be based solely on stated criteria and is irrespective of membership in an affiliation with any other organization or group. Chapters may not discriminate on any basis prohibited by law. Membership, once conferred,
